For Your Safety

Warning! Switch off, remove plug from mains
before adjusting, cleaning or if cable is cut,
damaged or entangled.

The blades continue to rotate for a few sec­onds after the machine is switched off.

Caution – do not touch rotating blades.

Electrical Safety

Your machine is double insulated for safety and re­quires no earth connection. The operating voltage is
230 V AC, 50 Hz (for non-EU countries 220 V, 240 V
as applicable). Only use approved extension cables.
Contact your service agent for details.

Extension cords/leads should only be used if they
comply with H05VV-F or H05RN-F types.

It is recommended for increased electrical safety to
use a Residual Current Device (RCD) with a tripping
current of not more than 30 mA. Always check your
RCD every time you use it.

For products not sold in GB:

WARNING: For safety, it is essential that the

B

mains plug 4 attached to the machine is fitted to the
power supply cable

The couplings of connection leads must be pro­tected against splashes and the coupling sockets on
the leads must be made of rubber or coated with rub­ber.

Fixing means for the connection leads must be used.
The power cord must be inspected for signs of dam-

age at regular intervals and may only be used if in
perfect condition.

a Bosch Service Centre.
Products sold in GB only: Your machine is fitted with

an approved 13 A (BS 1363/A) electric plug and is
protected by a 13 A fuse (ASTA Approved to
BS 1362).

If the fitted plug is not suitable for your socket out­lets, it should be cut off and an appropriate plug fitted
in its place by an authorized customer sercive agent.

The severed plug must be disposed of to avoid a
possible shock hazard and should never be inserted
into a 13 A socket elsewhere.

Adjusting the Cutting Height

C

Stop, release switch lever and wait until
the motor stops before adjusting height.
The blades continue to rotate for a few
seconds after the machine is switched off,
a rotating blade can cause injury.

For the first cut of the season, a high cutting adjust­ment should be selected.

Your machine has three settings that result to the fol­lowing cutting heights.

I = 20 II = 40 III = 60
